Long-term data on the structure of agricultural land (ALL) and sown areas by groups of agricultural crops in Kuzbass, presented in statistical collections and databases of the Federal State Statistics Service of the Russian Federation and the territorial body in the Kemerovo region-Kuzbass, served as the basis for the study. Target. Analysis of long-term data on the structure of agricultural lands, including reclaimed ones, data on sown areas, including by groups of agricultural crops, in the Kemerovo region-Kuzbass and determination of the general development trend in dynamics. Methods. When performing the study, methods of mathematical data processing, comparative analysis and visualization were used. Scientific novelty. Horizontal analysis of long-term data allowed the authors to assess the dynamics of the structure of sown areas of agricultural crops by groups in the Kemerovo region-Kuzbass. Groups of agricultural crops have been identified that demonstrate a significant change in their share in the structure of sown areas. Results. The general trend in the dynamics of the ZSN structure and the reasons for the decline in most indicators in Kuzbass have their own characteristics, but in general they coincide with the all-Russian ones. It has been established that with a general trend towards a decrease in the areas of conservatory crops, mainly due to their transfer to other categories, the rate of reduction of land for grain, leguminous, fodder and vegetable crops in Kuzbass is higher than the Russian average. And also with the identified general trend towards an increase in the share of industrial crops in the structure of sown areas in Kuzbass, rapeseed crops predominate, while in the Russian Federation the main share is made up of sunflower and soybean crops.
